CVE-2022-50671

RDMA/rxe: Fix "kernel NULL pointer dereference" error

State: Published
Severity: 7.5 High
Published: Dec 9, 2025
Updated: Oct 15, 2026
Reserved: Dec 9, 2025

Description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/rxe: Fix "kernel NULL pointer dereference" error

When rxe_queue_init in the function rxe_qp_init_req fails, both qp->req.task.func and qp->req.task.arg are not initialized.

Because of creation of qp fails, the function rxe_create_qp will call rxe_qp_do_cleanup to handle allocated resource.

Before calling __rxe_do_task, both qp->req.task.func and qp->req.task.arg should be checked.
